Hie guys I have changed a head gaske for Fordbuntam 1,3rowcam timing its ok but its boiling the pipes are geting filld with air nd they bcame hard they wnt to explod pls help

well does it hold pressure, no leaks. no pan full of water (engine pan)
1:bad cap rad.
2: bad thermostat or installed backwards
3: under filled. system. (air pockets not burped out)
4 : using only water, no AF50% only
5: bad pump belt slip to same.
6: rad,core tubes, clogged, use IR thermal gun to find super super easy. ask.
7: end RAD FAN overheated its dead or too slow.

Could be too much coolant in the system. Does it run dry on you if you run it for too long? There could also be trapped air in your cooling system which will work itself out with time.

Be sure the air is purged from system. The coolant pipe above the front valve cover near waterpump has a 7mm bleeder screw that will need to be loosened to purge air.

try flushing or replacing the heater core for some reason they get clogged

You need to find out from where it leaks - the fumes are nothing more than boiled antifreeze. Find the leak (start with the radiator) and fix it.

The heater core is probably clogged, or the valve that lets radiator fluid flow through the core is not working.

when it does not start you need to verify no fuel pressure, Most likely your problem is the wiring harness is bad which will destroy a new pump if the pump is not geting the voltage required.

hi, check for air geting in to the fuel line... the incolor fuel pipe imediately after the fuel filter (if u see air bubles means the air getting some how...vaseline is good to cover all the joints, i've dun it last spring and is good so far) ...if is not that u should change the air mass sensor (common problem with tdi's)...i've had same problem...now ok

Hi!
From your brief description it appears you have an air lock or maybe head gasket issues.
I presume/hope that recently you have had something to do with the coolant (Rad change or Thermostat) or maybe let water out to add anti freeze? what is needed is a system bleed.
O.k. when engine cool remove header tank cap (Where you add coolant) have the car on level ground start it up and leave it to idle, have plenty of very warm water available. Hopefully after the engine has reached operating temperature a bubbling and boil over will briefly occur. (Make sure you are well away from Coolant filler) top up the system with the very warm water, wait a good few minutes or more as it will possibly gurgle over again. If after a good while it stops then replace cap and hopefully problem sorted.
If the fault persists you may need to repeat process, If when you are doing this operation the water boils over profusely and a lot of air bubbles are seen all the time when warm the Head gasket may have fractured between cylinders pushing gases into the cooling system causing the air lock and overheating.
Final checks! Is the oil on the dipstick Creamy/Coffee coloured? Has the oil filler got gungy creamy gloppy stuff all over it? Is there oil in the coolant? From the exhaust pipe is there a considerable amount of Water dripping when engine running? and finally do the hoses go very hard become pressurised?
The above point toward Cylinder Head or Gasket failure.
Last thing, could the water pump be faulty? is there any coolant driping from behind it?
Sorry for the Epic!
Hope this helps?

no im a mechanic it sounds like that you have an air lock in the cooling system .i am familiar with ford freda and bongo and the design where the engine is is a bit far from the radiator ,so the problem with air locks magnifies.really the solution is just drain the water and refill it slowly while you are pressing and releasing,just repeat the action on the top radiator hose to get rid of any air trapping within the system,it's as simple as that really.you want it to have just water and no air as this will cause a blockage.
